The DBH 8355 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 55 mm shaft diameter, 90 mm housing diameter and 12.50 mm height place it in medium-sized transmission and rotating equipment. It is a wear part: when the lip hardens or a leak appears, it is replaced before damage reaches the bearing.

This item is a DBH 8355 radial shaft seal, with designation 8355 and the following dimensions: 55 mm shaft diameter, 90 mm housing diameter and 12.50 mm height. The indicated design is Kz, which corresponds to a single lip configuration with a retaining spring. The flexible lip runs on the rotating shaft and the outer metal case is fixed by interference in the housing. It is a sealing component designed for continuous service in environments with oil or grease.

It is used in gearboxes, pumps, electric motors, transmission shafts, rollers and process equipment where a shaft rotates inside a housing and the lubricant must be separated from the outside. It also appears in applications with splashing, dust or moderate humidity, where a well-chosen seal prevents premature bearing wear and reduces downtime due to oil loss.

To install it, verify that the shaft is clean, free of burrs or tool marks, and that the housing has no dents. Lubricate the lip before inserting it and seat the part perpendicular, without tilting it. If the shaft shows a worn track, it is advisable to evaluate a neighboring size or a seal with the lip in a different position. Selection depends on speed, temperature and lubricant type; with that data the appropriate variant is confirmed.

If you need a different size or an equivalent, send us code 8355 or the shaft, housing and height dimensions along with a photo of the part and the mounting area. With that we review alternatives within the same radial shaft seal category and confirm which option fits without modifying the housing. We can also verify whether the Kz design is the one that corresponds to your equipment.
